Embodiment Construction

[0025] As mentioned in the background art, the current way of parsing and processing function expressions in a compiled language environment is relatively complicated, which seriously affects the data processing speed of the terminal in the C / S architecture.

[0026] Specifically, regardless of the client or server in the existing C / S architecture, if the terminal is running in a compiled language environment, when receiving the function expression sent by the other end, it is necessary to write a special compiler, and The compiler is invoked to perform a series of complex processes such as lexical analysis, syntax analysis, and semantic analysis on the received function expression. It can be seen that in the prior art, when parsing a function expression in a compiled language environment, the processing logic is complicated and the efficiency is low.

[0027] In order to solve the above technical problems, an embodiment of the present invention provides a method for parsing a...

Abstract

The invention discloses an analysis method and device for a function expression in a compiled language environment, a storage medium and a terminal. The method comprises the steps of obtianing the function expression from the exterior of the compiled language environment; carrying out regular replacement operation on the function expression so as to analyze the function expression into a characterstring in a JSON format; and constructing a call tree based on the character string in the JSON format. Through the method provided by the invention, the analysis operation on the function expressionin a compiled language environment can be simplified, and the operation complexity is reduced.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for analyzing function expressions in a compiled language environment, a storage medium, and a terminal. Background technique [0002] In the client-server (C / S for short) architecture in the field of algorithms, there are some application scenarios where one of the client and the server needs to pass a function expression to the other for the latter to use in its own operating environment. Called in , where the function expression supports functions and four arithmetic operations. [0003] In some scripting languages ​​(such as JavaScript) environments, the passed function expression string can be executed directly. [0004] However, in a compiled language (such as C++ or Java) environment, this type of operating environment is not equipped with a parser, and the function expression string passed from the outside must be parsed before it can be called. Ho...
